Near infrared spectrometer
近红外光谱主要对应于含氢基团振动的倍频和合频吸收,因此近红外光谱仪可测量多数有机化合物的组分信息,并具有分析速度快、样品无损、绿色无污染等特点,广泛应用于食品、药品、医学、石油化工等多个领域。
The near-infrared spectroscopy mainly
corresponds to the frequency-doubled and combined-frequency absorption of
hydrogen-containing group vibrations. Therefore, near-infrared spectroscopy can
measure the composition information of most organic compounds, and has the
characteristics of fast analysis speed, non-destructive sample, green and no
pollution, and is widely used in Food, drug, medicine, petrochemical and other
fields.
